Carnegie Mellon researchers seek to control blood loss

PITTSBURGH Carnegie Mellon University's Matt Oberdier is developing a new hydrosurgery system to help physicians better manage excessive bleeding during surgery.

Oberdier, a Ph.D. candidate in biomedical engineering at Carnegie Mellon, said his system will be designed to help surgeons readily clear excess blood and control bleeding during critical stages involving brain operations.

"We are creating a device that will house a clear, hermetically sealed dome through which instruments may be passed, and a special pump to apply fluid pressure and monitor the flow to the surgical area,'' said Oberdier.

Surgeons need a clear view during brain operations because they have to navigate deep inside the skull and control very small blood vessels.

"About half of all surgeons' time is spent trying to control some level of bleeding during most operations,'' said James Burgess, a neurosurgeon at Allegheny General Hospital and an adjunct lecturer in Carnegie Mellon's Biomedical Engineering Department. "This new tool will save time and has the potential to benefit more than 35 million patients worldwide,'' said Burgess, Oberdier's co-advisor.

James Antaki, a professor of biomedical engineering at Carnegie Mellon, and Oberdier's co-advisor, said the future of biomedical engineering rests with the development of cutting-edge tools for physicians and hospitals. Antaki is part of an interdisciplinary team that developed a blood pump that provides up to six months of extended circulatory support for children and infants recovering from heart surgery or awaiting a heart transplant.
